Abstract. quan la mida de materials ptics ben coneguts es redueix al rang dels nan metres, apareixen noves propietats f siques. aix ha motivat l'aparici d'un gran inter s per la s ntesi i la caracteritzaci d'aquests nanocristalls, cobrint tots els vessants, des dels materials amb aplicacions l ser fins als materials per fen mens de conversi de freq .
In this paper, an attempt has been made to modify the micro sized silicon carbide powder into nano structured silicon carbide powder using high energy ball mill. ball milling was carried out for the total duration of 50 hours. the sample was taken out after every 5 hours of milling and it was characterized for its crystallite size, lattice strain, and percentage of crystallinity by using x-ray.
Nanostructured materials continue to attract attention because of their new and interesting properties, which are very different from their macrostructured equivalents. since the size of grain and surface differs, a better understanding of the microstructure, the mechanism of formation, and methods of controlling surface properties is necessary. in this study, nanostructured silicon carbide.
Produce silicon nanostructured powder in our laboratory. in this paper, we report the preparation and characterization of silicon nanostructured powder using dc arc-discharge system, in particular, with an emphasis on the production of high aspect ratio si nanostructures such as nanowires and nanotubes. silicon nanotubes.

The study of silane plasma deposition processes is important due to the large number of large area devices based on amorphous silicon. when transferring research results to production, deposition rate and uniformity are key issues. also, production facilities must avoid powder formation which could reduce device yield. the study of square-wave modulated discharges revealed that silicon.
